Targeting the P2X7 ion channel, a danger sensor for extracellular nucleotides, improves outcomes in models of inflammation, cancer, and brain-diseases. Antibodies and nanobodies have been developed that antagonize or potentiate gating of P2X7. Their potential advantages over small-molecule drugs include high specificity, lower off-target effects, and tunable in vivo half-life. Genetic fusion of P2X7-specific biologics to binding modules may enable targeting of specific cell subsets. Besides directly modulating P2X7 function, antibodies can also initiate specific depletion of P2X7-expressing cells. Adeno-associated viral vectors (AAV) can be used to express P2X7-specific antibodies in vivo to achieve long-lasting biological effects. Furthermore, if successfully targeted to P2X7-expressing cells, AAVs may enable modulation of the function of P2X7-expressing immune cells via encoded transgenic RNA or proteins.

A voltage-gated sodium channel subtype that mediates the sodium ion PERMEABILITY of CARDIOMYOCYTES. Defects in the SCN5A gene, which codes for the alpha subunit of this sodium channel, are associated with a variety of CARDIAC DISEASES that result from loss of sodium channel function.
A cytoplasmic receptor and peroxin that contains a series of TETRACOTIPEPTIDE REPEATS and binds to PEROXISOME TARGETING SIGNAL 1 (SKL-type). It is essential for protein import into PEROXISOMES; mutations in the PEX5 gene are associated with PEROXISOMAL DISORDERS such as ZELLWEGER SYNDROME.
A cytoplasmic receptor and peroxin that contains a series of WD40 REPEATS and binds to PEROXISOME TARGETING SIGNAL 2. It is essential for protein import into PEROXISOMES; mutations in the human PEX7 gene are associated with PEROXISOMAL DISORDERS such as Type 1 CHONDRODYSPLASIA PUNCTATA, RHIZOMELIC.
A purinergic P2X neurotransmitter receptor that plays a role in pain sensation signaling and regulation of inflammatory processes.
Voltage-gated sodium channel subunits that play a role in the assembly, expression, and functional modulation of the sodium channel. They form a heterotrimeric complex with the pore-forming sodium channel alpha subunits.
